I thought the paper was ok except for that spreadsheet question. Heres what i remember from it:
Mcqs Cant really remember the order
1. Weight
2. loop contracts into a circle
3. time constant = seconds
4. Open the switch
5. 4*10^-4 Wb
6. Particle is moving closer to the speed of light
7. 10MeV/c^2
8. To collide hadrons
(im sure i missed some question :P)
Structured
Proof was easy i got that and the wavelength was 2.something *10^-11
describing the velocity time graph was easy - you just have to say it accelerates firsts and then accelerates in the opposite direction and why ( due to the resultant force acting on the ball because of the electric force it experiences in the field)
The speed of the bat after collision was 0.56m/s (if you used 0.8) or 0.52m/s (if you used 0.77). Even though the difference in the KEs was small - there was still a difference therefore - inelastic (from the students conclusion)
However - am i the only person who noticed that the final KE > initial KE ???? Thats why they asked the about the uncertainty of the student measurement of the height x - the students value was too big because final ke cannot be greater than initial KE - thats impossible because energy is lost during the collision as heat or sound)
Spreadsheet - i managed to prove the first part - couldnt do D5 but i proved E6 using s=ut+.5at^2
Max radius= 2.9*10^-14
Conclusions of Rutherford expt - i think everyone knew this :P
The jelly question with the graph - it was a straight line and you have to find the negative gradient. The constant was 0.00625cm^-1 (or 6.25m^-1) (of course there would be a range for this answer because it depends on your graph)
Particl physics question was simple - for the conservation i guess you can talk about any 3 of 6 things that are conserved : Charge, Mass/Energy, Baryon Number, Lepton Number,Strangeness and Momentum
For the question with sulphur - the change in mass was 0.00233u or something which was much greater than the least count of the trap (0.00001u) therefore it can be measured
Sorry if i missed out something
